The ancient inheritance is the biggest secret of Gu Yan, which has collected countless exercises and combat skills, and many ancient inheritances have even saved Gu Yan's life in times of crisis, but Gu Yan knows very little about the specific origin and mysterious function of the ancient inheritance.

The ancient inheritance has the ability to record exercises and combat skills, and Gu Yan was only discovered not long ago, and it can see Gu Yan, and all the martial arts classics that are not collected in it are burned in the ancient inheritance.

Although the ability of ancient inheritance is not a means of defying the sky, it is extremely practical for Gu Yan, which can avoid many unnecessary troubles, and it is also very aspect.

After inspecting the three jade slips, Gu Yan once again focused his attention on the sarcophagus inside the Dark Demon Golden Ring, which was not large, and the materials and techniques of refining were also very ordinary, which made Gu Yan even more interested in it.

Such an ordinary sarcophagus, a demon saint like Mo Ye, how could he put it into the Dark Demon Golden Ring if he had nothing to do.

With full curiosity, Gu Yan also removed the sarcophagus from the Dark Demon Golden Ring, Gu Yan carefully looked at the sarcophagus and found that this sarcophagus was also engraved with a formation.

"Grandma's, there is actually a formation engraved on a coffin, is this sarcophagus also a special crystal or something demonic sealed inside?" Gu Yan muttered, it was the first time he had seen a coffin engraved with a formation.

After thinking for a moment, Gu Yan decided to open the sarcophagus to find out, and his right hand slammed out a palm towards the coffin lid, and the coffin lid, which was several feet thick, flew out directly, slammed into a boulder, and broke into several pieces in an instant.

At the moment when the coffin lid was blown away by the ancient rock, an extremely familiar coercion instantly emanated from the sarcophagus, which was extremely terrifying, and at the same time, a dark and pure demonic aura floated out from the sarcophagus.

Under this terrifying pressure, Gu Yan's legs sank directly under the ground, his shoulders seemed to be under the weight of hundreds of thousands of catties, the qi and blood in his body were churning, and his bones were rubbing with a "buzzing" sound.

"Could it be that there is really something evil sealed in this sarcophagus? Gu Yan was worried in his heart, and looked at the sarcophagus with a solemn face, but it was extremely difficult to see clearly, because the sarcophagus was wrapped in a ball of incomparably pure demonic qi.

At this moment, Gu Yan suddenly felt a hint of excitement coming from the Demon Eater Ring on his ring finger, as if the Demon Eater Ring was very interested in the contents of the sarcophagus.

The Demon Eater Ring is also an extraordinary thing, and Gu Yan doesn't know much about him, since he has the Demon Eater Ring until now, this is the first time that the Demon Eater Ring has taken the initiative to contact Gu Yan.

Gu Yan hesitated for a moment, his heart sank, and the Demon Devouring Ring on his ring finger slowly appeared, and as soon as the Demon Devouring Ring showed its face, it began to frantically devour the demonic qi that wrapped the sarcophagus, and at the same time, the terrifying coercion disappeared instantly.

The coercion disappeared, and Gu Yan was no longer suppressed, and with a sharp turn of his feet, he stepped out of the ground and slowly walked towards the sarcophagus.

The devouring power of the Demon Devouring Ring is so terrifying, the Demon Emperor Master's divine soul and demon body can be devoured in an instant, not to mention these demonic qi, in less than half a moment, the demonic qi that filled the entire valley was swallowed up by the Demon Devouring Ring.

Looking at the empty valley, a trace of regret and helplessness flashed in Gu Yan's heart, before he stepped into the depths of the valley, he had considered using the Demon Devouring Ring to devour all the demonic qi in the valley, even in the face of the demon puppet, if he used the Demon Devouring Ring, Gu Yan was confident that he could easily devour it.

But Gu Yan decisively gave up that idea, and he didn't hesitate to use the Beast Soul Talisman and didn't want to reveal the Demon Devouring Ring, because he was worried that once this Demon Devouring Ring came out, it would swallow up the demonic qi in the entire valley, and he also wanted to use the demonic qi in this valley to cultivate the Demon God Transformation.

In fact, as Gu Yan feared, as soon as the Demon Devouring Ring came out, in less than half an instant, it devoured the demonic qi in the entire valley.

At this moment, there was no monstrous demonic qi in the entire valley, and all the ancient rocks in the valley could be seen clearly, and the sarcophagus was still swallowing demonic qi, but it was much less than before.

"I want to see what is in this sarcophagus that can make the Demon Eater Ring so excited. Gu Yan said lightly and walked straight towards the sarcophagus.

As Gu Yan approached the sarcophagus, the reaction of the Demon Devouring Ring became more and more intense, and when Gu Yan saw the contents of the sarcophagus at a glance, he was instantly stunned, his eyes opened wide, and both eyeballs were about to protrude.

Inside this sarcophagus turned out to be a skeleton, a dark golden skeleton, as if it was made of metal, and each bone exuded a faint dark golden luster.

"I didn't expect that what was placed in this sarcophagus was the bones of the old thing of Moye, the bones of the Demon Saint, each of which was not inferior to an emperor-level high-grade crystal, containing huge energy, no wonder it could make the Demon Devouring Ring so excited. Gu Yan said in shock.

Looking at the dozens of Demon Saint bones in the sarcophagus, Gu Yan's heart could be said to be shocked, this is the bone of the Demon Saint, even if it is not refined, it is comparable to an emperor-level crystal, and it is even more powerful with the power of a saint, it is definitely a treasure.

Now Gu Yan finally understood why the coercion was so terrifying when the sarcophagus was opened, the coercion of a drop of Demon Saint Essence Blood was so strong before, not to mention the dozens of Demon Saint bones, Gu Yan felt excited when he thought about it.

However, Gu Yan was very entangled in his heart at the moment, these Demon Saint bones were priceless treasures, and if they were taken out and auctioned for at least one million top-grade barren stones, if they were handed over to the Heavenly Machine Holy Land, they would definitely be able to exchange for a large amount of cultivation resources.

Even if they are not sold or handed over to the Heavenly Machine Holy Land, if they are used to refine crystals, they can refine at least twenty emperor-level crystals, and they are also emperor-level crystals with the coercion of saints, which is enough to make the strength of Purple Saint Continent to a higher level.

However, the Demon Devouring Ring kept sending contact to Gu Yan, asking Gu Yan to give it these Demon Saint bones, as if these Demon Saint bones were of great use to it in repairing its own damage.

The Demon Devouring Ring was damaged Gu Yan knew that it seemed that the damage was quite serious, if these Demon Saint bones were allowed to be devoured, the terrifying energy contained in them would definitely be of great use to repair them, but Gu Yan was still a little difficult to choose.

If you were anyone, it would be difficult to choose at this time, the bones of the Demon Saint were so precious, it would be a pity to let the Demon Devouring Ring swallow it directly.

After hesitating and thinking for nearly a quarter of an hour, Gu Yan finally made up his mind, although he didn't know what the Eater Ring had and what it could bring him, but his intuition told him, but he wanted to take a gamble.

Gu Yan looked at the Demon Devouring Ring and said softly, "Although I don't know what kind of anti-heaven power you have, I know that you are by no means an ordinary thing and have your own spiritual sense, but I hope you don't betray or endanger me, otherwise, I will definitely destroy you!"

Hearing Gu Yan's words, a message came from the Demon Devouring Ring, "Master rest assured, the Ring Soul will not betray the master, and please believe me!"

Seeing this information in his mind, Gu Yan was shocked, he didn't expect that this Demon Devouring Ring actually had its own machine spirit, which meant that the Demon Devouring Ring was at least an imperial soldier, and it was also an imperial soldier with a complete instrument spirit.

Gu Yan was overjoyed, although he had a few imperial soldiers, but the body was extremely damaged, the machine spirit dissipated the mutilated imperial soldiers, and there was no one with a complete machine spirit, what he didn't expect was that this Demon Devouring Ring turned out to be an emperor soldier with a machine spirit, no wonder he was so excited.

Gu Yan nodded, and his divine sense responded, "Ring Soul, I believe in you, and I hope you are disappointed by me. ”

With Gu Yan's consent, the Demon Devouring Ring was extremely excited, and with a crazy devouring force, it directly rolled dozens of Demon Saint bones in the sarcophagus into the Demon Devouring Ring, and in an instant, the Demon Devouring Ring trembled violently, and a dark black light bloomed from the surface of the Demon Devouring Ring.

Previously, because of refining the Demon Slayer and others, some small cracks on the surface of the body were repaired a lot, and the pure demonic qi in the valley before had all the small cracks on its surface repaired.

Devouring dozens of Demon Saint bones again, the huge energy made the largest crack on the surface of the Demon Devouring Ring heal little by little, and at the same time, Gu Yan could also feel that the mysterious connection between himself and the Demon Devouring Ring was gradually increasing.

Although the Devouring and Refining Ability of the Demon Devouring Ring was terrifying, the dozens of Demon Saint bones were not ordinary things, and they had been refined for nearly an hour, and at this moment, Gu Yan could feel that the space inside the entire Demon Devouring Ring was full of a large amount of pure demonic energy.

And the biggest crack on the surface of the Demon Devouring Ring was also completely repaired at this moment, but Gu Yan knew that the damage to this Demon Devouring Ring was not only on the surface, but also the damage inside the ring was even more serious, and those pure demonic qi turned into huge energy, quickly repairing the damaged places inside.

Suddenly, the Demon Devouring Ring, which had been calmed down, trembled again, and a stream of pure demonic qi entered Gu Yan's body from the Demon Devouring Ring, Gu Yan's body shook, and he immediately meditated cross-legged, running the "Demon God Change" and began to frantically refine those demonic qi.

"Master, I know that you have also cultivated the Demon Dao Exercises, these demonic qi are refined by the Soul Ring, and they are more refined, so the master can take the opportunity to cultivate!"

As the Ring Soul said, this demonic aura was even purer than the demonic aura emitted by the sarcophagus before, and the energy contained was even greater.

Running the "Demon God Transformation" exercise and refining those pure demonic qi, the magic patterns on the surface of the ancient rock body are increasing at a speed visible to the naked eye, extending from Gu Yan's neck to the whole body one by one, and at this moment, only a small part of the body of the ancient rock is not covered with magic patterns.

Gu Yan's mood can be described as very excited, his original idea was to use the demonic qi in the valley to break through the first realm of the "Demon God Transformation" body skin transformation, and now with the help of the demon qi provided by the Demon Devouring Ring, the breakthrough of the body skin transformation is even smoother than Gu Yan expected.

A quarter of an hour later, the last circle of magic patterns was also successfully condensed, every part of Gu Yan's body skin was covered with magic patterns, and streams of pure demonic qi began to slowly seep into Gu Yan's flesh and blood, Gu Yan could feel that his blood and muscles were slowly turning black.

Suddenly, the demonic qi introduced by the Demon Devouring Ring at this moment also skyrocketed, and the speed of the exercise instantly increased several times, and the demonic qi covered every part of the ancient rock body, Gu Yan shouted, "The flesh and blood have changed, break it for me!" The demonic qi covering the body skin seeped into the flesh and blood of the ancient rock in an instant, and the body surface was no longer a circle of magic patterns, and the whole body was dark black.
